The quantum efficiency of a solar cell generally refers to the external quantum efficiency, which is the ratio of the output of the solar cell to the incident light, while the internal quantum efficiency refers to the output of the solar cell in relation to the absorbed light (incident light). light minus reflected light and transmitted light). In other words, measuring the internal quantum efficiency requires additional measurement of the reflectivity and transmittance of the solar cell, and then measuring and calculating the internal quantum efficiency and the internal quantum efficiency. the measurement can be performed on the same device
The hardware difference and cost performance are different.
1. The materials are different. Perovskite solar cells use perovskite materials, while quantum dot cells use nanocrystal materialssemiconductors.
2. The price/performance ratio is different. Perovskite quantum dot batteries are more cost-effective and affordable than perovskite solar cells.
